At Infrasense, we understand the importance of precision and safety in completing infrastructure projects, which is why we often utilize 3D Ground Penetrating Radar (3DGPR) for utility and obstruction mapping. 3DGPR surveys let us provide detailed imaging of subsurface utilities and obstructions without the need for lane closures. The 3DGPR data is combined with as-built…
The Infrasense SUE Team is hard at work on subsurface utility mapping projects across Massachusetts. Leveraging advanced tools like 3D ground penetrating radar (3DGPR), EMI utility tracers, and other geophysical methods, we continue to support our client’s projects with accurate and comprehensive utility maps. If you have an upcoming project where we can be of…
Subsurface Utility Engineering (S.U.E.) requires working together to plan safe and efficient surveys, which often means overnight shifts to minimize interactions with traffic. In addition to traditional utility mapping tools, Infrasense can deploy vehicle-based ground penetrating radar as part of SUE projects to report other subsurface conditions including pavement layer thicknesses and moisture ingress/ voiding.
In August of 2022, Infrasense performed an SUE QL-B survey to map the location of underground utilities of known and unknown origin adjacent to the Church Street bridge crossing Fall River in Bernardston, Massachusetts. The survey included the use of GPR and EMI tools as the primary detection instruments and GPS for positional accuracy. The…
Infrasense recently completed a subsurface utility engineering (SUE) project on Dorchester Avenue in Boston, MA. The initial phase of the project included reviewing existing site drawings (QL-D) and a site survey to identify the location of relevant site features (e.g., water valves, fire hydrants, manholes, and telephone poles (QL-C). The second phase of the project…
Infrasense recently completed a subsurface utility engineering (SUE) project in the vicinity of the four vent buildings that service the Sumner and Callahan Tunnels in Boston, MA. The project involved reviewing availability site drawings (QL-D), confirming the location of the site features (e.g., water valves, catch basins, manholes) (QL-C), and locating known and unknown utilities…
Infrasense completed a subsurface utility mapping project at a large industrial park in Tyngsboro, MA using a combination of ground penetrating radar (GPR) and electromagnetic induction (EMI) locating methods. The GPR equipment included a 400MHz ground-coupled antenna mounted to a cart with an integrated distance encoder and GPS unit. This GPR antenna is capable of…
In June of 2022, Infrasense performed an SUE QL-B survey to map the location of underground utilities of known and unknown origin along 2 miles of Route 16 in Mendon, Massachusetts. The survey included the use of GPR and EMI tools as the primary detection instruments and GPS for positional accuracy. The infield-located utilities, combined…
Infrasense completed a subsurface survey to map the location and position of an oil/water separator and drainage basin structure that had its access lids paved over during construction at the site. The rapid NDE survey consisted of using a portable, GPR Survey System manufactured by GSSI, Inc. to identify and map out the locations so…
Infrasense completed a survey to both locate embedded utilities and determine pavement thickness of a three mile section of road spanning Warren and Bristol, Rhode Island. The survey was carried out using a nondestructive technology, Ground Penetrating Radar (GPR), and thus required no cores or test pits to obtain the necessary information. A majority of…
